This release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Minor Changes 2477 8e1d2e9 Thanks @felixweinberger ! - Move the schema source modules (spec schemas, OAuth schemas, protocol constants) into @modelcontextprotocol/core and resolve them from there as a regular runtime dependency instead of bundling a private copy into each package. An application importing more than one of the packages now evaluates a single shared schema graph with shared object identity. @modelcontextprotocol/core gains a ./internal subpath (SDK-internal contract; may change in any release) and the four packages now version together. Patch Changes 2402 a400259 Thanks @felixweinberger ! - First beta release of SDK v2 with support for the MCP 2026-07-28 specification revision. See the migration guides for upgrading from v1 ( docs/migration/upgrade-to-v2.md ) and adopting the 2026-07-28 revision ( docs/migration/support-2026-07-28.md ). 2405 f172626 Thanks @mattzcarey ! -…","sponsors":[]}
